AP Photo/Sanford Police video via Zimmerman Defense TeamGeorge Zimmerman speaks to investigators at the scene of Trayvon Martin's fatal shooting a day later giving police a blow-by-blow account of his fight with the teen.

The video, recorded on Feb. 27, is Zimmerman's most detailed account yet of the incident. His attorney released the 20-minute tape plus audio recordings of police interviews as the defense approaches Zimmerman's second bond hearing on second-degree murder charges on June 29. In the recording, Zimmerman explained that Martin said, "You're going to die" and reached for Zimmerman's gun just before the fatal shooting.

The edited tape provided by ABC News shows Zimmerman giving his account of how the altercation escalated that night in Sanford, Florida:

"He said, 'Yo you got a problem?' I said, 'No, I don't have a problem man,'" Zimmerman told authorities. Zimmerman said as he reached for his cell phone, Martin approached him and asked, "You got a problem now?"

"And then he was here and he punched me in the face," Zimmerman explained.

Zimmerman went on to say he "stumbled" to the ground and Martin got on top of him, causing Zimmerman to scream for help. Martin then put his hand over Zimmerman's mouth and told him to "Shut the f____ up," he alleged.

"My head was on the cement and he just kept slamming and slamming it," Zimmerman told investigators in another segment of the video. "It felt like my head was going to explode, and I was just going to lose consciousness."

Zimmerman's head and nose were dressed with bandages during the recording.

Zimmerman said Martin noticed his gun as he pinned him to the ground, saying, "You're going to die tonight" before reaching for it. Zimmerman claimed he grabbed the gun before Martin and shot the teenager, then got on top and restrained him.

The Martins' attorney, Ben Crump, wouldn't respond directly to the video. He did tweet about the subject, writing "Everyone should review Zimmerman's objectively written statement in comparison to the 911 tapes which were previously released," according to the Huffington Post.

In the audio recordings released today, detective Chris Sereno described Martin as a "good kid, mild-mannered kid." He also told Zimmerman that the two dozen punches he claimed to take are "not quite consistent with your injuries."

While Zimmerman's story portrayed Martin as the aggressor, the teen's parents have claimed the opposite. They say Zimmerman followed their son as he walked through the gated community and they claim he was racially profiled, partly because he was wearing a hoodie.

David Hill, an Orlando-area defense attorney not connected with the case, told the Huffington Post that Zimmerman came across as being "straight-forward," not the "cop-wannabe" that he has been portrayed as.

However Blaine McChesney, an Orlando defense attorney who is also not involved in the case, told the Huffington Post that he has some difficulty envisioning parts of Zimmerman's re-enactment -- such as how he was able to reach for his gun with Martin on top of him. He also found it odd that Zimmerman used both arms to hold Martin face-down after shooting him.

"...It would have been more logical to hold Martin at gunpoint from a few feet away until police arrived," McChesney told the Huffington Post.
